ηππ model of X0 and a possible η-π resonance

open access: yes, 1966
An ηππ model of the X0 meson at 960 MeV is proposed through factorable π-π and η-π s-wave forces. The over-all dynamics is described by a three-body Schrödinger equation under a nonrelativistic approximation which is ...

Gjellestad and its Surroundings: What was known prior to the excavation of the ship burial?

open access: yesViking
The story behind the discovery of the Gjellestad ship burial is long and fragmented. In this chapter, we describe how knowledge of the prehistory of Gjellestad and its surroundings gradually developed over many generations, concluding with the use of ...

Effect of π-π interaction on high-energy π-p scattering

open access: yes, 1956
The object of this paper is to examine the possibility of explaining the second maximum in (π-p) scattering in the framework of the Tamm-Dancoff approximation for (π-p) interaction, by postulating a resonant π-π interaction in the ...

The T3(π, π) state of acridine

open access: yes, 1983
The 0---0 band maximum of the transition T3(π, π∗)←T1 (π, π∗) of acridine occurs at ≈10200±20 cm-1 in inert (n-hexane, benzene, CCl4), at 10220±20 cm-1 in polar (acetonitrile) and at 10170±50 cm-1 in ...
