Bu çalışmada, 1p halo çekirdekleri 8B ve 17F ve 2p halo çekirdeği 9C elastik saçılma açısal dağılımlarını açıklamak için alternatif potansiyeller araştırılıyor. Bu amaçla, proximity potansiyellerin on üç farklı yoğunluktan bağımsız ve bir yoğunluğa bağlı versiyonu çalışılıyor. Teorik sonuçlar birbirleriyle ve deneysel verilerle karşılaştırılıyor ve deneysel verilerle iyi uyumlu sonuçlar elde ediliyor.
