Enhanced electron-capture decay rate of 7Be encapsulated in C60 cages.

چکیده
The decay rate of 7Be electron capture was measured in C60 and Be metal with a reference method. The half-life of 7Be endohedral C60 ((7)Be@C(60)) and 7Be in Be metal (Be metal (7Be)) is found to be 52.68+/-0.05 and 53.12+/-0.05 days, respectively. This amounts to a 0.83% difference in electron-capture decay half-life between (7)Be@C(60) and Be metal (7Be). Our result is a reflection of the different electron wave functions for (7)Be@C(60) inside C60 compared to the situation when 7Be is in a Be metal.

E¡ect of pressure on the decay rate of 7Be
Beryllium-7 in Be(OH)2 gel was compressed in diamond-anvil pressure cells up to 442 kbar at room temperature. By counting the activity of 7Be, the decay rate for the conversion of 7Be to 7Li via electron capture was measured. The decay constant of 7Be, V, was found to increase, but the rate of increase decreased with increasing pressure. A quadratic regression of the data yields (V3V0)/V0 = (4....
متن کاملDependence of the decay rate of 7Be on chemical forms
The decay rate of 7Be depends on the electron density at the nucleus and therefore may vary with the chemical environments of the Be atom. Using a 100% efficiency high-purity germanium detector, the decay constants of Be in Be2C(OH2)4, Be(OH)2 and BeO have been measured at unprecedented high precision (of š0.01%), resulting in T1=2 D 53.69 d, 53.42 d, and 54.23 d, respectively. The observed dif...
متن کاملSite specific atomic polarizabilities in endohedral fullerenes and carbon onions.
We investigate the polarizability of trimetallic nitride endohedral fullerenes by partitioning the total polarizability into site specific components. This analysis indicates that the polarizability of the endohedral fullerene is essentially due to the outer fullerene cage and has insignificant contribution from the encapsulated unit. Thus, the outer fullerene cages effectively shield the encap...
متن کاملElectron - capture decay rate of 7 Be @ C 60 by first - principles calculations based on density functional theory
Carrying out a first-principles calculation assuming linear relationship between the electron density at Be nucleus and the electron-capture EC decay rate, we explained why Be@C60 shows higher EC decay rate than Be crystal, which was originally found experimentally by Ohtsuki et al. Phys. Rev. Lett. 93, 112501 2004 . From the results of the calculation, we found that there are inequivalent four...
متن کاملComment on “Influence of protons on the capture of electrons by 7Be in the Sun”
This paper suffers from conceptual difficulties and unjustified approximations that render its conclusions invalid. The influence of protons on electron capture by 7Be in the Sun is already included in the standard plasma screening correction to the density of thermal electrons at the 7Be nucleus needed for calculating the capture rate. Moreover, the approximation to the three-body wave functio...
