1 Energy release in alpha-decay 2 Consider a nucleus which is stable against decay by proton or neutron emission { the least bound nucleon still has (say) several MeV of binding energy. This nucleus may nevertheless still be able to decay by using the fact that if it can emit an alpha-particle (2He), it can use the binding energy of the alpha to supply the energy needed for the escape. That is,...

We extend the two-dimensional model of drug use introduced in Behrens et al. [1999, 2000, 2002] by introducing two additional states that model in more detail newly initiated (“light”) users’ response to the drug experience. Those who dislike the drug quickly “quit” and briefly suppress initiation by others. Those who like the drug progress to ongoing (“moderate”) use, from which they may or ma...

When a weak decay competes with a strong decay in a 3-level atom, some mechanism is necessary to occasionally stop the strong decay so the weak decay can be completed. Rule (4) provides that mechanism. Using this rule, a weak photon is emitted at the correct time for both the V and Λ configurations, as well as for the two cascade configurations.

this study aimed to examine the relationship between pigments and seed fall rate of iranian castor genotypes and genetic diversity, specifically 28 castor genotypes (27 native and 1 modified), a randomized complete block design with three replications was conducted in 2014 and 2015 at the research farm of islamic azad university in damghan, northern iran. during the growth period, the following...

When a new mdividual is formed (independently of the reproduction process) it inherits harmful iuutations. Moreover, new mutations are acquired even in the genetic code formation, most of them deleterious ones. This might lead to a time decay in the mean fitness of the whole population that, for long enough time, ,vould produce the extinction of the

The modern American poet Elizabeth Bishop’s craftsmanship is fully shown in the keen, delicate observation, ingenious musicality, pure and accurate poetic diction, rich and vivid images in her poems. Filling Station is a poem depicting a decayed family-run station, unified by the pervasive presence of oil, and complete with filth and beauty, disorder and order, hope and decay, masculine and fem...

In this paper, a hyperbolic differential inclusion with nonmonotone discontinuous and nonlinear term, which the generalized velocity acts as its variable, is studied and the existence and decay of its weak solution are obtained.

The potential of large scale Yb-loaded liquid scintillators as proposed for solar neutrino spectroscopy are investigated with respect to double beta decay. The potential for β−β− decay of Y b as well as the β/EC decay for Y b is discussed. Not only getting for the first time an experimental half-life limit on Y b decay, this will even be at least comparable or better than existing ones from dif...

In this paper, the semileptonic decays of heavy mesons are treated fully relativis-tically. By means of an effective vertex, the effect of Fermi momentum are included both at the inclusive and at the exclusive levels, and the spin of both parent and daughter particles are taken into account. The differential decay rates with respect to the lepton energy and momentum transfer are compared with d...
