Applications of gamma spectrometry
... 1) Statistical (starting at high state density) E1 transitions from the highest excitated states 2) E2 transitions near to Yrast line – not only inside rotational bands (because of crossing) → high number of transitions with small intensity – „quasicontinuum“ 3) Regular structure of rotational bands ...

Beta-decay studies at the N = 28 shell closure
... N = 28 since Ar and S isotopes are deformed but on the other hand the slope of the two neutron separation energy S1n seemed to indicate that 42Si has the characteristics of a doubly magic nucleus, as 48Ca. However recently the same authors adjusted their interaction to reproduce single particle stat ...

Conservation of Energy Discussion (from 16.3) Here is a brief
... In physics, K(t) = 12 m|v(t)|2 is called the kinetic energy of an object. Thus, for ANY force vector field along a flow line, we have WORK = K(B) − K(A) = the change in kinetic energy. SECOND, now let F also satisfy our mathematical definition of conservative, that is, F = ∇f (x, y, z). In physics, ...
