An  analysis of theoretical spectra to experimental data yielded the mass and width of , respectively, and, where a possible population of and a small p-orbit capture contribution are taken into account. The calculations show that by the variation of  potential parameters (range parameter, , and strength parameter,), the mass and width of  are almost independent of the potential parameters.
