Lifetimes of yrast states in ^{51}Ti, ^{52}Ti, and ^{52}V

چکیده
The 'Li and 'Li bombardment of "Ca in conjunction with recoil distance measurements has been used to measure the mean lifetimes of excited states in "Ti, "Ti, and "V: in "Ti, 2754-keV level (r = 1.2 + 0.4 nsec) and 2344-keV level (7 = 13.9+2.3 psec); in "Ti, 3027-keV level (v=36,7 + 6.3 psec); in "V, 2541-keV level (~ = 7.7 + 0.5 psec). The y-ray decay schemes and lifetimes are consistent with an interpretation involving yrast states of the (77 1f7/2) (v2p3/2 1f„„2 pl /, ) configuration where n = 2 or 3 and m = 1 or 2. The experimental level energies and B(E2) values are compared with shell model calculations by Boric and Ogawa.

Lifetimes of the (f_{7/2})^{3} 15/2^{-} states in ^{51}V and ^{43}Ca and (f_{7/2})^{2} 4^{+} states in ^{50}Ti and ^{42}Ca via heavy-ion recoil-distance-method measurements
The recoil-distance method has been used in conjunction with heavy-ion reactions to measure the following mean lifetimes: v= S.O+ 0.6 and 34.1+1.5 psec for the (f7/2) ('2 ) states at 2700 keV in 'V and at 2754 keV in Ca, and 7=7.7+1.5 and 5.1+0.4 psec for the (f7/2) 4+ states at 2676 keV in OTi and at 2752 keV in Ca, respectively. The resulting B(E2) strengths are interpreted in terms of effect...
متن کاملSU„3... symmetry breaking in lower fp-shell nuclei
Results of shell-model calculations for lower f p-shell nuclei show that SU~3! symmetry breaking in this region is driven by the single-particle spin-orbit splitting. However, even though states of the yrast band exhibit SU~3! symmetry breaking, the results also show that the yrast band B(E2) values are insensitive to this fragmentation of the SU~3! symmetry; specifically, the quadrupole collec...
متن کاملA strategy for degradation of 2,5-dichlorophenol using its photoelectrocatalytic oxidation on the TiO2/Ti thin film electrode
In this work, the photoelectrocatalytic (PEC) degradation of 2,5-dichlorophenol can be used for its removal from aqueous solution. To study this activity, a TiO2 thin film modified titanium sheet (TiO2/Ti) was fabricated by anodizing Ti plates using a two electrode system under the constant bias voltage of 20 V for 20 min in a solution of 0.2% (v/v) HF followed by calcinat...
متن کاملThymus development and infant and child mortality in rural Bangladesh
BACKGROUND Data from West Africa indicate that a small thymus at birth and at 6 months of age is a strong and independent risk factor for infection-related mortality up to 24 and 36 months of age, respectively. We investigated the association between thymus size (thymic index, TI) in infancy and subsequent infant and child survival in a contemporary South Asian population. METHODS The study f...
