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
نویسندگان
چکیده
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 effective charges for different model spaces.

Lifetimes of yrast states in ^{51}Ti, ^{52}Ti, and ^{52}V
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 ...
متن کاملOn Codes over $\mathbb{F}_{q}+v\mathbb{F}_{q}+v^{2}\mathbb{F}_{q}$
In this paper we investigate linear codes with complementary dual (LCD) codes and formally self-dual codes over the ring $R=\F_{q}+v\F_{q}+v^{2}\F_{q}$, where $v^{3}=v$, for $q$ odd. We give conditions on the existence of LCD codes and present construction of formally self-dual codes over $R$. Further, we give bounds on the minimum distance of LCD codes over $\F_q$ and extend these to codes ove...
