Abstract
Gelişigüzel yürüme modelinin çiftçekirdek'in (N-Z) evrimindeki parçacık taşınma dinamiği çeşitli varsayımlarla çalışıldı. Parçacık taşınma olasılıklarında taşınan parçacığın (a) çiftçekirdek’in enerji korunumunu sağlıyan herhangi bir enerji düzeyinde olması, (b) enerji düzeyinin bir öncekinden ancak 1p-1h kadar daha karışık olduğu, (c) ilk enerji düzeyinin 1p-1h kadar yükseltgenmesi gözönüne alınmıştır. Fiziksel olarak bu varsayımlar, sırasıyla hiçbirşekilde, kısmen ve tamamen tek-gövde işlemine karşılıktır. Yukarıdaki her durum için Pauli kısıtlaması kuralı enerji düzeylerinin sayımında gözönüne alınmıştır,
Discrete Random Walk calculations of the (N-Z) evolution of a liquid drop dinucleus are reported for various assumptions about the trasfer dynamics. Transition probabilities are assumed which correspond to the transferred nucleon's being able to reach (a) any energy conserving state of the final dinucleus, (b) any energy conserving state more complicated by not more than lp and lh than the initial state, and (c) any one-particle one-hole excitation of the initial state. Physically these assumptions correspond to restricting the transfer, not at all, somewhat, and totally to be a pure one-body process. In every case, the Pauli exclusion principle is honored in the allowed final states. One finds that the assumption (c) generally leads to predictions easily distinguishable from those of (a) and (b), which do not differ substantially.
